    ►► http://Magnet4Power.Net -The Levitron spins and surfs on magnetic waves! Pass your hand above, underneath, and around the top. It will continue to spin and float only touching air! The LEVITRON floats free in space, supported only by therepelling magnetic force produced by permanent magnets.

    Discrepant Event-The Rattleback 01:02

    Discrepant Event-The Rattleback

    by (1/23/08) 20,852 views

    A rattleback, also known as an "anagyre", "celt", "Celtic stone", "rattlerock", "spin bar", "wobble stone" or "wobblestone" and by the product names "ARK," "Bizzaro Swirls," "RATTLEBACKS," "Space Pet" and "Space Toy," is a semi-ellipsoidal top which will spin on its axis in a preferred direction. But, if spun in the opposite direction, it becomes unstable, "rattles", stops and reverses its spin to the preferred direction. This spin-reversal motion seems, at first sight, to violate the angular-momentum conservation law of physics. Moreover, for most rattlebacks, the motion will happen when the rattleback is spun in one direction, but not when spun in the other. These two peculiarities make the rattleback a physical curiosity that has excited human imagination since prehistorical times.

    A Broken Heart For Valentine's Day 01:13

    A Broken Heart For Valentine's Day

    by (1/24/08) 18,365 views

    Watch my heart get broken just in time for Valentines Day. A marshmallow filled chocolate heart is placed into a vacuum and allowed to expand. Then I let my heart get crushed when the air is let back in. Kind of like what happens in life.

    HOT ICE Alternative 01:01

    HOT ICE Alternative

    The "Hot Ice" reaction is amazing, but messy and can only be used once. A great reusable alternative of a supersaturated solution are chemical hot packs that you can buy from a camping store. They contain a solution of sodium acetate that can be reset in less than an hour. They are also good as hand warmers, but why would you buy those?

    Insubordinate Tops

    Insubordinate Tops

    These tops don't work. I should return them. These hemisperical tops flip themselves over and spin. Here is a short video of my inverting spinning top. When spun the top actually will invert itself and spin on the handle. Not a magic trick.

    Muscle Wire (Nitinol)

    Muscle Wire (Nitinol)

    Sometimes called the Smart Alloy, Muscle Wire or Memory Metal, is an alloy that "remembers" it shape. You can reshape the wire, but when heated it returns to the preset shape. Ever wonder how someone bends a spoon with their mind? Same metal.

    Bond Energy

    Bond Energy

    by (1/4/08) 22,726 views

    A difficult concept for many students to understand is the energy involved in breaking and forming bonds. A hydrate is a substance that has water bonded to it. In order to dehydrate you must add energy (endothermic) to break the bond to water. When hydrating you are forming a bond to water and will release energy (exothermic). This visual demonstration reinforces the concept.

    Hydrate Video Lab 02:53

    Hydrate Video Lab

    by (1/4/08) 16,931 views

    Please watch and comment on my video lab I created. I am trying to get an idea of how I could use video labs with my chemistry course or website. I guess this would be good for students who are out of school for long periods of time, schools without chemicals, lessons when a teacher is out or something else. Please let me know what you think. About the experiment This experiment is intended to introduce students to hydrated compounds. These compounds have water molecules coordinated in their chemical structures. Examples CuSO4*5H2O, BaCl2*2H2O, and NaC2H3O2*3H2O. Notice each formula has a "*" between the compound's formula and the number of water molecules that are coordinated in the structure. the "*" represents a weak chemical bond known as a hydration bond. This bond is usually easily broken by heating the compound.

    Grape PLASMA 01:33

    Grape PLASMA

    Yes, plasma. You have seen a match make plasma in the microwave. You have seen a compact disc light up. Now you are going to see why it is dangerous to put grapes in the microwave.
